So far it has been regarded that Ischnura spp. is univoltine species in Poland. In 2010 the situations pointing out the emergence of the second generations were observed. In 2011 the studies designed to provide this evidence were conducted. A new and isolated pond (2x2 m, depth to 40 cm) was created in March in order to eliminate the possibility of the emergence of the first generation. It was situated near two shallow water bodies where in 2010 the larvae of Ischnura pumilio were found. In 2011 dynamics of the population in the new pond, two near shallow water bodies as well as in one large and deep water body were studied. The results confirmed the second generations of both species in the new pond and two shallow water bodies in its vicinities. Data from the large and deep water body did not confirm the emergence of the second generation of Ischnura elegans but also did not deny it. Metamorphoses lasted from the beginning of May till the end of August, with the peak in the second half of May. The time of larval development could be elongated by different water temperature than in small water bodies. However, the length of the development in experimental conditions at the temperature of 20–27°C is 60–70 days, and these temperatures prevailed for most of the season in the shore zone of this water body. Therefore, one can not exclude the possibility of development of the second generation in it – especially that it would explain the period of metamorphoses lasting up to four months. The full development of the second generation of Ischnura pumilio in the dug up pond lasted up to 60 days. This is the shortest development time found in the wild in Central Europe, similar to that of the development of I. pumilio in southern France, and the data from the breeding of other species of the genus (I. verticalis – 58 days, I. elegans – 60–70 days). The time of full development of the second generation of I. elegans in this water body was up to about 100 days. However, this water body was colonized by I. elegans reluctantly and the result may be unrepresentative. The time of development of the second generation of I. elegans may be much shorter, as indicated by the population dynamics in a shallow water body situated near the dug up pond. Data obtained during the research and a number of late records of I. pumilio indicate that the occurrence of the second generation of this species does not belong in Poland to rare exceptions. The arrangement of late records rather indicates the possibility of the emergence of the second generation in a large distribution area of the species in the country. Few observations of individual juveniles of I. pumilio in the half of September, and in one case 17 days after the record of the last juvenile specimen at the site, indicate the real probability of the emergence of even the part of the individuals of the third generation which requires further study.

The paper discusses the records of 10 new sites of Nehalennia speciosa in eastcentral Poland. Sites 4–6 and 7 are located in the landscape more or less agriculturally transformed converted and do not have continuous forest buffering zone. In Poland, the habitat of N. speciosa without the typical continuous forest buffering zone have been previously known only from a few sites so far. Data in this study indicates that their number is probably higher in Poland than previously thought. A relatively low trophy of peat bog and pools despite the agricultural use of their catchment area probably results from the presence of aeolian/poor fluvioglacial sands in the ground. Identified habitats of N. speciosa mostly refer to acidic fens with abundant Sphagnum (sites 1–3, 5, 7, 10), and acidic fens without or small amount of Sphagnum (sites 4, 6, 8, 9). Particular fragments of habitats occupied by N. speciosa were situated near open surface of water bodies (sites 1, 3, 4, and probably a few more) as well as far from the influence of water bodies, as a shallow flooded peat bog (sites 2, 5, 6–10 and probably at others at some places). Water bodies at sites 1–3, 6, 7 and probably 5 had peat excavation origins. Formations of helophytes inhabited by N. speciosa (with probable or confirmed larval development) can be divided into two groups – monospecies formations: Juncus effusus (sites 3, 4, 5, 10), Carex rostrata (sites 1, 4), Carex elata (sites 6, 9), Carex lasiocarpa (site 6), Carex vesicaria (site 9); and mixed ones (where space structure is formed by two helophyte species): J. effusus + C. rostrata (sites 2, 4), J. effusus + C. vesicaria (site 10), C. elata + C. lasiocarpa (sites 6, 9), C. lasiocarpa + J. effusus (site 7), C. rostrata + C. lasiocarpa (site 2), C. lasiocarpa + Eriophorum angustifolium (site 8). The formation of J. effusus with larval development has been found for the first time in Poland. C. elata as the leading plant element was known so far only from two sites discovered after 2009 as well as C. vesicaria. Data in this paper and other recent records of N. speciosa in oldglacial areas show that the elements different than Carex limosa/lasiocarpa are more often inhabited in Poland than it was given in older data. Secondary habitats as well seem to be inhabited more often. The occurrence of imagines was also found within shallow and temporarily flooded marginal zones of peat bogs; at site 3 also at land. Larval development was not found in those zones. Vegetation used by imagines at the discussed marginal zones consisted of J. effusus, Eriophorum vaginatum, Carex canescens, however, mainly: Molinia caerulea, Glyceria fluitans as well as short grass unidentified to the species level. At sites 1–3, 4, 9, imagines at marginal zones occurred at higher densities than in the zones of larval development (maximum: up to 20 individuals per 1 m2 at site 3). Perhaps it is caused by favourable microclimatic conditions at temporarily flooded marginal zones as well as the presence of suitable structure of vegetation. Dispersion of imagines towards the marginal zones is in several cases certainly enhanced by the increase in water level, which causes thinning of vegetation on the actual surface of the peat bog (where larval development takes place) and shallow flooding of vegetation in the marginal zone. It is possible that the dispersion towards the marginal zones may be increased at sites 3 and 4 by not entirely suitable spatial structure of swaps of J. effusus in the development zones. Existence of imagines aside of larval habitats may occur more frequently than it was suggested by previous data, especially in habitats with greater fluctuations of water level.

Coenagrion armatum (CHARPENTIER, 1840) belongs to the critically endangered species in Poland. The main reasons for its regress are: drying out the habitats due to the climate and anthropopression as well as eutrophisation and the changes of space structure and species composition of veg- etation associated with this (BERNARD et al. 2009). The number of sites of this species in Poland is underestimated (BUCZYŃSKI et al. 2011). In this paper there are two new records of C. armatum from the southern Podlasie and the eastern Masovia, with giving co-occurring dragon*y species (* – native species undergoing the whole development cycle, # – probably native species). The site nr. 3 is situated outside the presumed range of the occurrence (BERNARD et al. 2009). This is the ;rst record of the species after several years in Masovia (TOŃCZYK et al. 1998) and the third record to the west of 22°E after 2002 (BUCZYŃSKI et al. 2011; SAMOLĄG 2002). In the light of the last records about Dark Bluet in Puławy and Jabłonów (BUCZYŃSKI et al. 2011), the record in Masovia shows that there are more sites outside the presumed range of the occurrence and the lack of data is the result of not only the rarity of the occur- rence itself but also the lack of directed searches. The sites 1–2 probably dry out in the periods of low level of ground waters. The records of this species in such water bodies shows its high mobility and ability to fast colonize of new habitats.

The authors give 17 new sites of Nehalennia speciosa discovered in the years 2010–2011 in central–eastern Poland. This data is essential due to poor level of studying of this area and the species itself: stenotopic, under protection and very strongly threatened in Poland (EN category on the Red list of dragonflies of Poland). Species co-occurring with Sedgling were also given, indicating autochthonous species (marked with * symbol) and probably autochthonous (#). Among new sites 7 ones have situated in the eastern part of Masovia and 10 in the northern part of the Lublin District. They fill the gap between sites in northern Poland and the Łęczyńsko-Włodawskie Lake District and the areas of Kozienice. Therefore the state of maintenance of the species in the central-eastern part of the country is much better than it was suggested earlier (Bernard et al. 2009). Other discoveries in eastern Poland also confirm this fact (Buczyński et al. 2012; Czachorowski, Czachorowski 2009; Daraż 2011; Michalczuk 2012). The localities of Sedgling known before and new ones probably do not form the isolated range island but they belong to the extension of its compact main part situated in northern Poland. This is even more likely that at least in eastern Masovia there are numerous peat bogs located in forests similar to those described in this paper. This suggests the existence of a large number of yet unknown sites of N. speciosa which can form compact concentrations on which the analysis of satellite maps and geological maps of the Quaternary seem to indicate. In Poland N. speciosa inhabits: I. narrow zone of floating and waterlogged mats of vegetation on the boundary of open water Key Words. Odonata, Nehalennia speciosa, Sedgling, E Poland, new record, distribution area, habitat. table of lakes and small water bodies, and II. at least partially flooded parts of Sphagnum peat bogs and fens, usually at their small depression. Habitats of the first type are dominating (Bernard, Buczyński 2008). Among the localities we studied, we observed two types of environments, however, the rarer second type was more often (Bernard, Buczyński 2008). The preferences of imagines of N. speciosa towards Carex sp., Carex rostrata, Carex lasiocarpa and Eriophorum vaginatum were observed. New data shows that the number of localities in potential gaps of the range of N. speciosa can be large. Therefore taking a look for this species in other areas where such studies have not been conducted is needed.

Coenagrion armatum is a Siberian species whose south-western boundary of its distribution area goes through Poland. Formerly, it passed through the western part of the country. In the last 30–40 years it moped back ca. 300 km due to climatic and anthropogenic environmental changes. Currently, it runs through eastern regions – its putative form is shown on Fig. 1. The authors give five new sites of the species (Fig. 1). Breeding populations are probably at sites 1–3 (good habitat conditions, usually the large numbers of imagines) and less likely at site 5 (a water body partially dries out). In Puławy (site 4) a single imago was recorded in an unusual environment (a river slope), however, the complexes of water bodies in the valleys of the River Kurówka and Wisła are located nearby. The sites 4 and 5 are the first known from over 10 years in Poland which are located to the west of 22°N. They confirm the hypothesis of Bernard at al. (2009) about the existence of scattered relict populations outside this line. Probably there are more of them but a short and early flight period of C. armatum is the cause of its overlooking in faunistic studies. Nevertheless, the sites 1–3 are important because they confirm the form of the current species distribution area which was determined approximately due to the lack of precise data. The authors suggest the evaluation program as well as passive and active protection of C. armatum. It would be particularly important due to the regress and strong threats of the species in the neighbouring countries of Poland from the west and south – Poland is an important refugium of this species in Central Europe.
